hisi_sas: add v2 hw support for >4 SATA phys
This patch adds support for directly attaching SATA disks to phy
4-8. The problem was that only registers concerned with phy 0-3 were
being considered in sata_int_v2_hw(). The issue was not detected
previously as the development board only exposed phy 0-3; the new board
provides access to 8 phys.
